Title: Film thickness measuring apparatus
Inventor: KONOUCHI OSAMU
IPC: G01B11/00
Filed: 1990-11-13
Abstract: PURPOSE:To improve the measuring accuracy while reducing the measuring error of the reflectivity by providing optical filters of different transmittances, and decreasing the illumination outside the measuring area as compared with that inside the measuring area on a sample. CONSTITUTION:The luminous flux from a white light source 1 forms an image on an aperture diaphragm 3. The numerical aperture of an illuminating system is determined by the size of the aperture diaphragm 3. The luminous flux presses through an optical filter 4 at the conjugate position with a sample 8 and is cast to the sample 8. The casting amount of light to the sample 8 is corresponding to the characteristic of the filter 4, and therefore the intensity of the illuminating light is large in the vicinity of the measuring area, whereas the intensity is small in the periphery of the measuring area. Then, the light reflected by the sample 8 is guided to a TV camera 14 and a pin hole 12. Since the amount of flare is generally proportional to the casting amount of light in the periphery, the reflectivity error, that is, the measuring error of the film thickness can be restricted to 10% or so. Moreover, it becomes possible to measure a considerably thin film with high accuracy if the sensitivity of the TV camera 14 is adjusted to the quantity of light at a part where the intensity is weak.

Title: Method and apparatus for decomposing thin film on semiconductor substrate
Inventor: MAEDA AYAKO
IPC: G01N31/00
Filed: 1986-12-23
Abstract: PURPOSE:To enable only a thin film on one side of a semiconductor substrate to be decomposed efficiently, by vaporizing hydrofluoric acid solution within a sealed container and exposing to the vapor only one side of the semiconductor substrate arranged horizontally. CONSTITUTION:Each wafer 16 is disposed on a wafer support 15 with the surface to be decomposed on the upside. The wafer supports 15 are recieved in a rack 13 by sliding them along grooves 12. The rack 13 receiving the wafer supports 15 carrying the wafers 16 is disposed within a sealed container 1. A beaker 3 within the container 1 is filled with hydrofluoric acid 2 and the cover 1a of the container 1 is closed to seal up the container. After several hours at room temperature, the sealed container 1 is filled with vaporized hydrofluoric acid 2. The vapor of hydrofluoric acid 2 enters into the rack 13 from gaps of the rack and is brought into contact with the top face of each of the wafers 16, whereby a thin film on this top face is decomposed. Since only one side of the wafer is exposed to the vapor of hydrofluoric acid and only the thin film on said one side of the wafer is decomposed, there is no need of collecting decomposing solution, unlike conventional methods. Accordingly, the period of time required up to the decomposition can be decreased substantially.
